Description

  The present invention relates to an optical information reading device having a function of optically reading an information code such as a bar code or a two-dimensional code, and an output device for the information code.

  In recent years, mobile terminals such as mobile phones and digital cameras have become highly functional, and an increasing number of terminals can be connected to a network. However, since these mobile terminals have limited operation members, for example, it is very troublesome to input parameters such as an ID and a password for accessing the network. In addition, since some knowledge of the network is required for setting these parameters, it is difficult for users who lack network knowledge to set the parameters themselves.

  Therefore, as one of the methods for setting these parameters without input by the user, by adding an information code reading function to the portable terminal, these parameters are converted into information codes and output to the display device. The user can set the information by reading it using the information code reading function of the portable terminal.

As a method of setting system parameters of the optical information reader, there is a technique of automatically setting these parameters by reading a converted two-dimensional bar code (QR code), which is one of information codes ( Patent Document 1).
JP 2003-85474 A

  However, for example, when setting a confidential parameter such as a password for connecting to a network in the reading device by the above-described method, any mobile terminal having a mobile terminal information code reading function can be confidential only by reading the code. Parameters can be retained and set, which is problematic in terms of security.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a technique for generating a parameter for setting an electronic device in a simple operation and safely in terms of security. is there.

In order to solve this problem, for example, an information processing apparatus of the present invention has the following configuration. That is,
An information processing apparatus for creating the parameter for an electronic device comprising predetermined imaging means and processing means for processing according to the parameter,
Input means for inputting parameters for the electronic device;
Encryption means for encrypting parameters input by the input means and generating encryption information;
And an image output unit that generates and outputs a visible image to be captured by the imaging unit of the electronic device based on the encryption information obtained by the encryption unit.

  According to the present invention, it is possible to generate a parameter for setting an electronic device with simple work and safely in terms of security.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

  In the embodiment, an example will be described in which the present invention is applied to a personal computer (PC) as a setting information input / output device and a digital camera capable of reading an optical information code as a device to be set.

<Description of digital camera configuration>
FIG. 1 is a block diagram of a digital camera according to an embodiment. The digital camera 100 is configured to capture a subject image via an optical system (imaging lens) 10. The optical system 10 can be configured as a zoom lens (a lens that can change a shooting angle of view). Thereby, an optical zoom function (so-called optical zoom) is provided. The digital camera 100 can further be configured to have an electronic zoom function (so-called electronic zoom) by electronically cutting (trimming) an image captured by the image sensor 14. The digital camera 100 may be configured to have only one function of optical zoom and electronic zoom. Further, the optical system 10 may be replaceable.

<Description of personal computer>
FIG. 3 is a block diagram of the PC 300 in the embodiment. In the figure, a PC 300 has the following configuration including a CPU 301 that controls the entire apparatus, a ROM that stores a BIOS and a boot program, and a RAM that is used as a work area of the CPU 301.

  The HDD (hard disk drive) 304 stores in advance an OS (operating system) 304a, the digital camera setting program 304b in the embodiment, and a digital camera DB file 304c referred to by the digital camera setting program 304b. The digital camera DB file 304c stores a back image for each model of the digital camera to be set and coordinate positions of various switches provided on the back surface (details will be described later).

  A keyboard 305 and a pointing device (for example, mouse (registered trademark)) 306 are used to input characters and give various instructions. In accordance with an instruction from the CPU 301, the display control unit 307 performs a drawing process on the built-in video memory and a process of outputting the image data stored in the video memory to the display device 308 as a video signal. The display device 308 is a CRT or a liquid crystal display device. A network interface 309 is used to connect the PC 300 to the network, and enables transfer of print data to a printer existing on the network and access to various servers on the network.

<Description of digital camera settings>
The digital camera 100 and the PC 300 in the embodiment have been described above. Next, a setting method for connecting to the wireless LAN in the digital camera 300 in the embodiment will be described below.

  The reason why the digital camera 300 has a wireless LAN communication function is to transfer a captured image to a file server on the network or to print it with a printer on the network.

  However, even if hardware for connecting to the wireless LAN is provided, various settings are required when performing the communication. Normally, in order to connect to an IEEE 802.11 series wireless LAN, an ESS-ID (Extended Service Set Identifier) that is a network identifier of the wireless LAN and a Wep key that is an encryption key for preventing leakage are used. Various settings such as a channel and an infrastructure mode or an ad hoc mode as a communication method are required. Since the encryption technique is publicly known, description thereof is omitted here.

  Here, for ESS-ID and Wep Key, it is necessary to input individual characters constituting the character string. A possible means of inputting these is to display a list of characters on the display panel (liquid crystal display panel) that a digital camera normally has, select the desired character by operating the cursor with the cross key, and then press the enter key. It will repeat the operation. However, since it is a simple operation unit compared to the full keyboard of the PC 300, the operation is complicated, and it is difficult for a user who does not know the technical meaning of each parameter.

  Therefore, in the present embodiment, the administrator creates a two-dimensional barcode (QR code) including setting parameters, and the digital camera user decodes and sets the two-dimensional barcode (QR code) by the user of the digital camera. It was. However, if it is a user of a digital camera having a wireless LAN function and a two-dimensional barcode decoding function, even an irrelevant third party can connect to the wireless LAN. A security problem occurs. Therefore, this setting parameter is once encrypted with a secret key, and a two-dimensional barcode is created with the information obtained as a result. If the secret key can be shared only by the administrator and the authorized user, even if the third party obtains the two-dimensional barcode by some means, it is possible to make the decryption impossible even to the setting parameter.

  In order to realize the above, first, the processing of the PC 300 in the embodiment will be described with reference to the flowchart of FIG. 7 and FIGS. 4 to 6. The flowchart of FIG. 7 shows the processing procedure of the digital camera setting program stored in the HDD 304 of the PC 300. Of course, it is assumed that the OS has already been started.

  First, when the administrator gives an instruction to start the program using the pointing device 306, a setting window 400 shown in FIG. 4 is displayed in step S1.

  As shown in the drawing, input fields for each setting item of ESS-ID, WEP KEY, Channel, and Config are displayed. Since the setting items ESS-ID and WEP KEY input a character string, a text box is displayed, and the setting items channel and Config are displayed in a combo box format for selecting from predetermined values. . As for WEP KEY, the character string of the key input result by the keyboard is stored in the RAM (RAM 303) to prevent peeping, so that the number of key inputs can be determined but the type of each input key cannot be determined. "*" Is displayed.

  The administrator sets each setting item using the keyboard 305 or the pointing device 306 (step S2).

  The completion of the setting for each item is indicated by clicking the “Next” button shown in the figure. If it is determined that this button has been clicked (step S3), the process proceeds to step S4. If the “Cancel” button is clicked, this process is terminated.

  When the process proceeds to step S4, a secret key input window 500 shown in FIG. 5 is displayed instead of the setting window 400. Here, first, the pointing device 306 is operated on the combo box 500 to input (select) the model of the digital camera to be set (step S5). In the figure, “DSC-10000 shot” is selected as the model name (model name) of the digital camera. Here, a combo box is taken as an example, but input may be performed from a keyboard.

  When the model name of the digital camera is selected, a back image of the corresponding digital camera is retrieved from the digital camera DB 304 stored in the HDD 304 and displayed in the image display area 501. At this time, the coordinate positions of the various switches (buttons) on the back and the codes assigned to the switches are also read, and predetermined marks are displayed at the respective positions of the back image indicated by the coordinate positions.

  Note that the switch corresponding to the coordinate position stored in the digital camera DB 304 excludes the shutter button, the power button, and the switch that holds the slide position. Since the shutter button is a special switch (described later) and the slide switch keeps its state, it will not be necessary to describe the power button. The other switches are turned on when pressed and turned off when released, so that they can be handled in the same way as a normal keyboard, and are handled as those capable of inputting a secret key. However, in the case of a digital camera provided with a dial, a character code may be assigned in the rotation direction.

  The administrator inputs a secret key by clicking a cursor (not shown) linked to the pointing device 306 at each desired mark position displayed in the back image, and clicking (Step). S6). At this time, the same switch may be continuously clicked, and the order and the number of inputs are not limited. However, in order to make it possible to determine how many times the switch has been operated, a predetermined mark (“*” in the embodiment) is displayed in the column 502 in accordance with the number of inputs to the switch.

  In this way, when the key input using the back image of the selected digital camera is finished, the administrator clicks the “Next” button at the bottom of the window, so that the secret key (internally the code string) is displayed. Is held) (step S7 becomes YES).

  Thereafter, the process proceeds to step S8, where each parameter set in the window of FIG. 4 is converted into a predetermined format (for example, a series of data delimited by an appropriate delimiter), and the secret key specified in the window of FIG. Encrypt to obtain encrypted information. Next, in step S9, two-dimensional barcode image data is created from the encrypted information. Then, the process proceeds to step S10, in which the photographing window 600 shown in FIG. 6 is displayed, and the created two-dimensional barcode is displayed in the image display area 601 therein. Then, the display window is imaged (captured) with the digital camera to be set. If the “print” button is clicked (step S11), the two-dimensional barcode is printed and the process is terminated.

  The processing in the PC 300 in the embodiment has been described above. Next, processing of the digital camera 100 in the embodiment will be described with reference to the flowchart of FIG. Note that the processing described below is based on the operation of the display panel and each switch of the digital camera 100.

  First, in step S21, it is determined whether or not a wireless LAN setting is instructed. A wireless LAN setting instruction is displayed on a menu and selected from the menu. If it is determined that the instruction is other than setting of the wireless LAN, the process proceeds to step S22, and corresponding processing is performed (for example, normal shooting).

  If the setting of the wireless LAN is instructed, the process proceeds to step S23, a message for prompting the photographing of the two-dimensional barcode is displayed on the display panel, and the press of the shutter button 710 is awaited in step S24. The image taken at this time is a PC screen or printed matter. However, at the time of shooting, the strobe is turned off, and the shutter speed is slower than the vertical synchronization signal (60 to 80 Hz in a normal CRT). This is to eliminate the influence of reflected light from the screen and to capture an image of the entire display screen. In addition, the display is displayed with a high contrast in preparation for imaging the display screen.

  When the shutter button is pressed, imaging is performed, and the secondary barcode is decoded in step S25. If it is determined in step S26 that the decoding process has failed due to the absence of a two-dimensional barcode in the captured image, step S23 and subsequent steps are repeated.

  If the decoding of the secondary barcode is successful, the process proceeds to step S27, and a message prompting the input of the secret key is displayed. Then, the original function of all the switches that can be the secret key input target is invalidated, and the process proceeds to step S28, which is a process for determining whether or not the switch is simply turned on.

  In this step S28, every time the switch is turned on, a corresponding code is generated and stored. Then, in step S29, the input is continued unless it is determined that the shutter button has been pressed.

  If it is determined that the shutter button has been pressed (not photographed here), the decryption process of the information of the decoding result of the two-dimensional barcode is performed according to the input and stored code string (step S30). It is determined whether or not the encryption / decryption is successful by determining whether or not the information obtained by the encryption / decryption processing is in a predetermined data format (step S31). If it is determined that the decryption is unsuccessful, an error is displayed in step S12, and the process is terminated. If the encryption / decryption is successful, the wireless LAN of the communication unit 110 is set according to the obtained parameters, and registered in the non-volatile memory 56 to store and hold the setting contents (the next time it is started up) The configuration of the wireless LAN is initialized with the registered contents).

  As described above, according to the present embodiment, the setting parameter created on the PC is encrypted, and the result is displayed or printed out in the two-dimensional barcode format, thereby preventing the setting parameter from leaking. Is possible. In addition, unlike the normal character input operation, the digital camera side can be operated with attention to the order of pressing the switches and buttons provided on the operation unit, and the setting is completed, making the operation simple, In addition, the wireless LAN can be set without technical knowledge of the setting parameters.

  In addition, according to the embodiment, the input of the encryption private key is an image of an actual digital camera to be set (in the embodiment, only the back surface is used, but in order to use the switch provided in the upper part, This can be done using an image), so that it does not hinder the operation of the secret key when performing decryption.

  In the embodiment, the setting by the two-dimensional barcode has been described as an example. However, for a user who has sufficient technical knowledge about the wireless LAN, the user can select normal character input or two-dimensional barcode shooting. Anyway.

  Further, in the relationship between the switch position and code of each model of the digital camera stored in the digital camera DB 304c, it is desirable that “code” does not overlap for each model of the digital camera. The reason is that, in the case of the same manufacturer, the arrangement of the operation switches on the back tends to be the same or similar even in different models. That is, encryption / decryption can be prevented from succeeding except for the same model as the selected digital camera.

  Also, the parameters set in FIG. 4 may be saved as a file and used next time. In this way, when creating a two-dimensional barcode for another model, the file can be read, then the name of the other model can be set and the secret key can be entered. can do.

  In the embodiment, the setting of the wireless LAN of the digital camera has been described. However, the target to be set is not limited to the wireless LAN, and the target device may be any device that includes an imaging unit or can be connected to an imaging unit. It is not limited to cameras. In short, the present invention is applicable when information that needs to be prevented from being leaked is imaged and set by a corresponding device.

  Furthermore, as described in the embodiment, since the main processing of the present embodiment is in a program installed in the PC 300, such a program is naturally within the scope of the present invention. In general, a computer program can be executed by setting a computer-readable storage medium such as a CD-ROM in a computer and copying or installing the computer program in a system.
